Nowadays, the growth in the diameter of the rotors and the power capacity of the machinery require the application of constant monitoring to predict failures and reduce maintenance activities. These activities prevent emergency stops and failures that require the replacement of components; however, these operations involve a high cost. The system presented in this paper integrates a fast data processing method that can analyze monitoring signals in real-time. The overall system includes a set of sensors for the measurement of acceleration, angular velocity, temperature, voltage, electrical current, and oil quality. The system presented is able to produce a frequency spectrum with a length of 8192 points. The FFT module was implemented in a FPGA (Field Programmable Gate Array) and it generates in real time, the frequency spectrum. This system adjusts the dominant frequencies to the wind turbine velocity.

we revive the application of operando NMR technique in the study of LMBs. The combination of AFBs and operando NMR completely avoid the interference of lithium metal anode on the analysis of electrochemistry related Li metal, and thus observe the deposition and dissolution processes of lithium metal during cycling in real-time. Combining with the practical battery configuration and the novel data-processing method, we can operando monitor the evolution of capacity loss caused by the dead Li metal and SEI during the whole cycling process

AbstractMonitoring small size area deformations calls forincreasingly precise data with greater space and time resolution.To this aim, a GPS data processing method designedfor wireless networks of mono-frequency GPS receiversis proposed. The different steps of the method areexplained: the GPS processing is first detailed with the designof parametric and stochastic models, their inversionby an extended Kalman filter and the mitigation of themain errors: multipath. A parsimonious radio data transferprotocol is then proposed. It allows a real-time positioningthanks to a wireless transfer of GPS carrier phasesdata from receivers to a processing computer. Finally themethod is tested on a network of mono-frequency receiversdeveloped by the French National Mapping Agency (IGN).Tests prove its ability for real-time positioning with a fifteenreceivers network, and a precision under the centimeterlevel is reached.
